SPECIFICATION forming part of Letters Patent No. 609,156, dated August16, 1898.

Application filed January 15, 1898.

To all whom it may concern:

Be it known that 1, JOHN T. MEATS, of Taunton, county of Bristol, Stateof Massachusetts, have invented an Improvement in Looms, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters and figures on the drawings representinglike parts.

This invention relates more particularly to that part of the loommechanism called the take-up, whereby the cloth is taken up as by theoperative without stopping the loom.

By the application to the loom of my present invention, to behereinafter described, the weaver cannot speed the take-up abnormallywithout at once stopping the loom, the take-up mechanism being soconnected with stopping means for the loom that the former cannot bethrown out of gear without effect ing the operation of the latter.

I have also devised novel devices whereby the cloth is wound by contactwith and un-' derneath the take-up roll, the operativebcing enabled toremove the cloth-roll at any point of its downward movement as it iswound without the exertion required to unduly compress a spring orsprings, as has been common heretofore.

Various other novel features of my inven tion will be hereinafterdescribed in the speci fication and particularly pointed out in theclaims.

Figure 1 is a partial left-hand side eleva tion of a loomwith myinvention embodied therein. Fig. 2 is a partial front elevation thereof.Fig. 3 is a plan viewof some of the devices shown in Figs. 1 and 2,110be described. Figs. A and 5 are enlarged views, in side and Serial No.666,743. N m del-l front elevation, of the let-back pawl, of novelconstruction. Figs. 6 and 7 are enlarged .views, partially in sectionand in side eleva tion, respectively, of the clutch forming a part ofthe connections between the take-up and stopping means. Figs. 8 and 9are front and side views, enlarged, of a portion of the controllingmeans for the loom-brake. Figs. 10

and 11 are side and front views of modified devices at the loom side foryieldingly sup porting the cloth-roll. Fig. 12 is an enlarged front viewof a portion of the lay to show a novel device for regulating thepressure ex erted upon the shuttle by the shuttle-binder; and Fig. 13 isa transverse sectional view thereof on the line at m, Fig. 12, lookingto the left.

The loom-frame A, breast-beam A the main driving-shaft A, having fastand loose pulleys A A thereon, and a brake-disk A may be and aresubstantially all of well-known or usual construction, the take-npmechanism being actuated in usual manner from either the cam or thecrank-shaft of the loom, and herein I have shown a bevel-gear a on thecam-shaft A in mesh with a similar gear a, fast on an intermediate shafta suitably supported and provided at its outer end with a worm a butshown in Fig. 1.

p The worm is in mesh with and positively drives the wormgeara",rotatably mounted on a shaft a (see Fig. 6,)supported in suitablebearings on the loom side, said shaft having fast thereon at its innerend a pinion a, which drives the gearing between it and the gear I)",fast on the shaft of the take-up roll B. H

As shown in Fig. 6, collars 2 3 prevent the worm-gear of from movinglongitudinally on the shaft a said gear having on its inner face aclutch member a (shown as toothed or serrated in Fig. 6) to at timescooperate with a similar clutch member a, secured to or form ing a partof the holding or detent wheel a", longitudinally movable on thetake-up-actuating shaft (1 and keyed thereto, asat a to rotate with it.r

The hub a of the detent-wheelfla? has an annular groove thereinto beentered by lugs 4. of a yoke like foot on a vertical rockshaft a, Figs.1, 2, 6, and '7, mounted in an upright bearing 1%, shown in Figs. 1 and2 as depending from the holding-plate N, provided with the usualholding-notch n for the shipper-lever S A knock-off lever b, pivoted atb on the holding-plate N, (see Figs. 1, 2, and 3,) operates in usualmanner to throw the shipper out of the holding-notch upon failure of thefilling, the inner end of the lever engaging the usual weft-fork plate.(Not shown.) When the filling fails, the knock-off lever is actuated inusual manner, swinging to the right, Fig. 3, releasing the shipper,which is thrown by its controlling-spring S, actuating the beltshipper(not shown) to ship the belt and stop the loom.

The upper end of the rock-shaft a has fast thereon a laterallyextendedarm a, connected by a link a with the knock-off lever 19, the linkhaving downturned projections 5 5 to embrace the arm, while at its otherend said link is permanently secured to a seat b on the knock-0ft leverby a suitable bolt 6.

It will be obvious from the foregoing that if the take-up-actuatingshaft a be speeded up by the operative manually to improperly increasethe length of the cloth being woven the clutch member a. will be movedto the right, Fig. 6, rocking the shaft (L14 to swing the arm atforward, such movement of the latter acting at once through theknock-off lever b to effect the stoppage of the loom. It will also beobvious that when the knock-off lever is actuated by failure of thefilling the clutch mechanism will be operated to release the take-uproll from continued operation, and in connection with the take-up I mayuse an adjustable let-back pawl, (shown separately in Figs. 4 and 5,)which operates to let back the take-up roll a predetermined amountwhenever the detent-wheel a is unclutched fromthe actuating-gear a Thepawl c is longitudinally slotted at its upper end at o to receiveloosely a pin at, carried by ears nibetween which the pawl slides, saidears being erected on the depending bearing 47%. An adjusting-screw c isextended through a threaded boss 0 on the end of the pawl and into theslot c',and the amount which the pawl will let back is regulated by theposition of the inner end of the said screw, it being evident that thepawl will hang down by its weight as far as permitted by the screw,which then bears on the pin a. The greater the play permitted the pawlbetween the end of the screw and the adjacent end of the slot thegreater the amount let back. To prevent the pawl from leaving thedetent-wheel a when the latter is moved sidewise to throw it out ofgear, I have provided the pawl'with flanges 0 which extend over eachside of said detent-wheel, while permitting the lateral movement of thelatter.

The brake-sheave A is adapted to be engaged by a brake-shoe d, Fig. 1,upon release ofithe shipper, said brake-shoe being mounted on a bentlever D,..fulcrun1ed on the loom side at d near the periphery of thesheave, the long arm of the lever D extending to the front of the loomand having mounted upon it an actuating-weight W, as herein shown. Areleasing-rod d is attached to the lever D, and at its upper end saidrod has a catch 61 Fig. 9, the lip 61 of which normally engages theupper edge of an opening a in the holding-plate N, the shank of thecatch passing up through said opening.

The knock-off lever 12 has an ear b thereon, straddled by the bifurcatedend of a dog d pivoted on the ear by a pin d the hook-like end of thedog engaging the preferably beveled end of the lip of the catch (1 asclearly shown in Fig. 9, when the loom is running. While the catchengages its support the lever D is held lifted, maintaining the shoe 01away from the sheave A but when the weft fails the releasing movement ofthe knock-off lever 1) acts through the dog (1 to disengage the lip ofthe catch from the plate, releasing the catch and permitting the weightto rock the lever D and apply the brake.

The journals of the take-up roll B are mounted in upright standards B,one of which is shown in Fig. 2, within the loom sides, secured to thebreast-beam A and to brackets B said standards being longitudinallyslotted at B to form guides for sliding supports 13 for the journals ofthe cloth-roll B Each support is shown as a plate extended through theslot B and provided at its front end with a projecting handle b the rearend having an enlargement or weight b at the back of the standard, whilea lateral ear 6 is formed on the support at the base of the handle. Pinsor lugs 8 and 9 extend oppositely from each side of the support and bearupon the front and back faces of the standard, the pins being so placedthat when the front end of the support is lifted it is cramped orclamped, as it were, on the standard.

A strong spring S below the breast-beam has attached to the end thereofa cable or other flexible member 12 which passes over a guide I) on thestandard B, at its upper end, and thence to the lug b on the cloth-rollsupport B to which it is suitably attached. The spring holds thecloth-roll up under the takeup roll 13, and as the roll of clothincreases in diameter it pushes the supports down along the standards,the increasing weight of the cloth being provided for by the increasingtension of the spring. The spring acts to lock the supports on thestandards at any point until the tension of the spring is overcomeeither by sufficient weight or pressure brought upon the cloth-roll orupon the handles b of the supports.

Whenever it is desired to remove the clothroll at any point of itstravel, a slight pressure upon the handles 19 overcomes the springtension, releasing the supports, so that the supports can be moveddownward as far as which act upon the shuttle-binder B desired. Thepressure upon the handles being removed, the tension of the spring atonce acts to again lock the supports B at the desired point, so that theremoval of the cloth roll is permitted at any desired place in itstravel along the standards. This capability of removal at any point is anovel feature, so far as I am aware, and a very valuable feature of myinvention.

In Figs. 10 and 11 I have shown a modified form of support for thecloth-roll, the modification, however, consisting in the manner ofapplying the spring to the sliding automatic locking-supports B, thelatter being of the form and character hereinbe-fore described andoperating in the same way on the slotted upright standards B, and it maybe noted in this connection that the slot at the lower end of eachstandard is enlarged, as shown in Figs. 2 and 11, to permit thewithdrawal from or the insertion of the support into the slot.

In the construction shown in Figs. 10 and 11 the lateral lug or ear 6 isomitted, and instead the support has on its inner side an ear I)", cutout or recessed, as at 6 (see dotted lines,) to receive the reduced andconvexed tip f of a tube f, which slides telescopically in a tubularguide f, suitably secured to the standard B,the tubes f and f containinga spring S one end of which bears against the upper end of the tube f,the lower end of the spring resting on the bottom of the tube or guidef. As the weight of the cloth on the roll B increases the supports Bwill descend, as hereinbefore described, and the tube f will telescopeinto its guide f gradually compressing the spring S Bydepressin g thehandles 2) of the supports, as before described, the support is unlockedand can be readily pushed down far enough to permit the supports toagain automatically lock at any point on the standard, so that the rollof cloth may be removed when desired.

The salient feature in the cloth-roll-s upporting mechanism in eitherconstruction shown is the capability of the removal of the roll at anypoint of its travel and the automatic looking of the roll supports ontheir upright guides.

In Figs. 12 and 13 I have shown a convenient device for regulating thetension of the shuttle-binder spring, the lay A being shown as providedwith the usual rock shaft h, mounted in bearings 72. depending from thelay, said rock-shaft carrying the usual binderfinger h, only one ofwhich is herein shown, The rock-shaft It carries the dagger 71 for theantismash or protective mechanism,of usual form, and the hub 71 of theshuttle-binder finger h is held securely in adjusted position on therockshaft by means of a suitable set-screw 71. The hub it is toothed orserrated at one end, as at 771 (see Fig. 12,) to engage thecorrespondingly-toothed end m of a nut m, rotatably mounted on therock-shaft, and to which one end of the'controlling-spring S is 'at-'tached, the other end of the spring being attached to one of thebrackets h as herein shown. In order to vary the tension of the springand thereby the pressure of the binder upon the shuttle, it is onlynecessary to rotate the nut m in one direction or the other to tightenor loosen the spring. This is a very convenient and ready means forvarying the tension.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is l 1.
